Abstract

O An optical sensor of the barrier type for air jet weaving looms comprises two equally orientated, parallel photoelements and two very thin total-reflection optical prisms aligned with the photoelements and insertable between and the reed blades in order to deviate the light rays between said photoelements so that they cross the weft yarn passage channel in the reed.
